Paroxysmal Supraventricular Tachycardia

Alternate Names : PSVT, Supraventricular Tachycardia, SVT, Paroxysmal Atrial Tachycardia

What can be done to prevent the condition?

Someone who experiences PSVT can be taught simple methods to help stop it. These techniques can be as simple as holding one's breath or straining down very hard. Some people may take medications only when an episode of PSVT occurs, while others may take medication daily to prevent episodes.

PSVT can be prevented by a procedure called radiofrequency catheter ablation. In this procedure, a specially trained heart specialist or cardiologist places a small tube or catheter in the heart to find the circular electrical pathway. Radio waves are used to eliminate the abnormal electrical pathway. This usually prevents any more episodes of PSVT from occurring.

What are the long-term effects of the condition?

PSVT is usually more of a bother than an illness. Many people who experience PSVT can stop the abnormal rhythm with the techniques taught by their healthcare provider. The abnormal heart rhythm may correct itself. Other people may need to go to the emergency department to get medication for episodes of PVST.

What are the risks to others?

There are no risks to others.
